Isn’t the ‘Brutus’ running a 46 liter BMW airplane engine from 1924 that provides somewhere between 500-750 hp? The Mavis is using a WWII era bomber engine producing nearly 1500 hp. It’s also riding on a rather exquisite 1930 Bentley chassis, while the Brutus is using a truck chassis﻿ from 1908… How is the Brutus ten times better? Certainly, it may be the cooler car, but that’s a matter of opinion.

This engine has 2 exhaust valves per cylinder, on an aircraft only one pipe was used for each pair of exhaust valves so only 6﻿ pipes were used on each side, in this car each valve has it’s own separate pipe.

This is the Wings and Wheels event, right?﻿ I went to that some years ago, before the Packard-Bentley was even built. I’d forgotten slightly what it was about, but after seeing this I think a visit to a future event is on the cards.
